Patent DE-2637178-A1 (DE)
Title: High pressure and temp. generated by thermonuclear reaction - in shell-type magnet with annular plasma chamber and tangential igniter
Inventor: STROBEL CHRISTIAN DIPL ING
IPC: G21B1/00
Filed: 1976-08-18
Abstract: High pressure and temp. is generated in gases by initiating and maintaining a thermonuclear reaction in a hydrogen plasma in a hollow annulus. A thermonuclear pump is used to initiate and maintain the reaction. In the add., a shell-type transformer is used for enclosing the hollow annulus. This transformer has a laminated iron core carrying the prim winding; outside this is the torus contg. the hollow annulus, which is evacuated and then charged at low pressure with a hydrogen mixt. (deuterium + tritium). The outside casing of the transformer is constituted of a number of segments with radial insulation layers between them to prevent a sec. annular current being generated in this region; the core and segments are closed to a magnetic circuit by upper and lower plates contained in the housing, and upper and lower cover plates. The prim. and the torus constitute an induction system; after preheating, the gas in the annulus is concentrated by the magnetic system towards the central axis of this annulus, resulting in further intense heating. The preheating is effected ohmically by the induced short-circuit current, while the later heating is produced by current pulses of a winding contained in the prim. The axis of the thermonuclear pump enters the torus tangentially to the hollow annulus. This thermonuclear pump injects hot helium plasma to initiate fusion in the already preheated plasma contained in the hollow annulus.

Title: Mechanism for rotating IC engine valve - has centering ring round rotation inducing annular component
Inventor: DRENKHAHN KURT
IPC: F01L1/32
Filed: 1976-09-08
Abstract: The head (3) of a poppet valve has circumferential grooves containing spring loaded balls (2). An inclined flat annular spring (1) with grooves (7) rests on the balls and is forced down by the valve collet (5) which is pressed down by the valve spring (6). As the valve moves up or down the inclined spring forces the balls round circumferentially to the ends of their grooves so that they rotate the valve. A centering ring (8) is fitted round the flat annular spring (1). This absorbs sideways forces and prevents the annular spring being displaced sideways. If there is a cage between the spring and the balls the centering ring is fitted round the cage. It serves the same purpose of preventing sideways displacement.

Title: Measuring flow characteristics of fluids for medical purposes - instrument includes metering capillary, pressure detectors and plunger pump
Inventor: WEBER GERHARD PROF DR
IPC: G01N33/487
Filed: 1976-12-24
Abstract: Technique for clinical and pharmaceutical applications for determining the flow characteristics of a fluid such as blood or serum, uses a capillary tube. The fluid to be measured is drawn from the space in which it is contained, in the human body or another source, and passed through a metering capillary in the metering track to a buffer store. From there, for the measurement of its viscosity, it is returned through the capillary at a constant speed for a definite interval of time, to the space from which it was derived. The suction and compression of the fluid to be measured is effected through an auxiliary, inert fluid such as a dissolved infusion. Pref. materials used for construction of the appts. includes polyamide and stainless steel. The flow characteristics of the fluid can be measured easily and quickly, and without the fluid being lost. The device can be cleaned without being dismantled, and once the connection is made, the tests can be carried out successively over a long period, e.g. during a clinical operation.

Title: Segregating mixed bed resins - by fluidising into layers of different densities for separate regeneration
Inventor: LIMPER KLAUS DIPL ING
IPC: B01J49/18
Filed: 1977-01-26
Abstract: A method of sepg. (partly) used cation and anion particles in a mixed bed consists of fluidising the bed so that it is sepd. out into two different layers according to the different densities of the particles; drawing off the upper layer by means of the fluidising medium until just above the boundary layer between it and the lower layer; and extracting the remainder of the upper layer by creating a sink effect in the remaining liq. above the boundary layer by causing it to flow in a vortex. Used for stationary mixed bed filters in which the ion exchange and cation exchange resins need to be removed when they are fully exhausted or partially used. The method enables the bed to be exactly divided into different layers according to the differing densities of the particles and prevents remixing of the particles, even at the boundary layer between them.
